I've been building kernels from the kernel.org sources since, hmm, 2.2.12, including many of Alan Cox's prereleases, with very few problems.
In contrast, the few times I've bothered with the PPC development tree sources, I've had lots of problems. The impression I've gotten is that most changes made to the PPC-only tree are for supporting newer machines, and probably work fine on those newer machines, but break on older systems (I have a PowerCenter 132). Having a separate tree for development purposes is a good thing, and people who want to experiment with new features or unusual hardware should probably be using that kernel. But it's very important that everyone else use the main kernel source, and report any bugs in the main tree so they can be fixed. If the two trees aren't being kept in sync, then we, the users, have a problem, and we need to encourage the developers to keep things up to date in the main tree.
